5x-10=3x+40
5x=3x+50
2x=50
x=25
5*25=125
125-10=115
angle AEB=115
Hope this helps :)
Answer:
H0: p = 3.5
H1: p < 3.5
Step-by-step explanation:
We are told that past studies have indicated that the percentage of smokers is estimated to be about 35%, but with the new smoking cessation programs that have been implemented, it is believed that the percentage of smokers has been reduced, we must propose our null and alternative hypotheses, which would be the following:
Null hypothesis: H0: p = 3.5
Alternative hypothesis: H1: p < 3.5
Answer:
108 cm²
Step-by-step explanation:
The formula for the lateral area of a pyramid such as this is ...
LA = 1/2Ps
where P is the perimeter of the base (6·3 cm = 18 cm) and s is the slant height (12 cm). Putting the given values into the formula gives ...
A = 1/2·(18 cm)·(12 cm) = 108 cm²
___
The formula gives the total area of the 6 triangular faces. Each face has an area of ...
A = 1/2·b·h = (1/2)(3 cm)(12 cm) = 18 cm²
Then the total area of the six triangles is ...
6 · 18 cm² = 108 cm²
